CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 328,098, dated October13, 1885.

Application filed August 6, 1685. Serial No. 173,795. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM R. WILooX, of Mansfield, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImproved Safety-Brake for Incline- Railway Cars; and I do hereby declarethe following tobe a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same, reference being had to theaccompanying drawings, which form part of this specification.

My invention relates to an improvement in a safety-brake forincline-cars, the object of the same being to provide means whereby anincline-car may be stopped immediately should the rope used for raisingand lowering the car break; and with this end in view my inventionconsists in certain details of construction and combination of parts, aswill be more fully explained, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a plan view of my improvement,showing the eccentrics placed at either side of a large T- rail,together with such mechanism as is required to operate the same. Fig. 2is a side view of the same attached to the frame of a car. Fig. 3 is across-section of the track.

To put my invention into practice, I place a large Trail, a, between therails of the track b,and continue the same throughout the entire length.On the top ofthis T-rail is placed at regular intervals a series ofrollers, c, for supporting the cable 61 used in operating the car.Beneath the car, and rigidly attached thereto by suitable braces, e f,are vertical posts each having an eccentric, h, loosely attached theretoand arranged at aproper distance from the T-rail ain the middle of thetrack I). About the posts 9 are wound spirally a stout spring, t, oneend, j, of which is attached to the post g, and the other, It, to theeccentric h, which serves to revolve the latter until brought tobearagainst the vertical part of the T-rail a. The projections Z on theside of the eccentrics it serve to keep the same in place, and are madeadjustable and detachable. From the cable d used to operate the car twobranches, n, are secured to the eccentrics h, which prevents the samefrom revolving and taking hold of the T-rail (I. Should the cable d,used for operating the car, part or break, the eccentrics h revolve inthe direction indicated by the arrows until they come in contact withthe T- rail a, and the car moving in the opposite direction tightens theeccentrics until the friction is so great as to stop the car and preventfurther descent, and the cable d is again attached to the car. Theeccentrics may be detached from the rail a by moving the car a shortdistance up the track.

Having thus described myinvention, what I claim, and desire to secure byLetters Patent, is

In a safety-brake for incline-railway cars, a T-rail, a, placed betweenthe rails of the track b, the eccentrics h, revolving loosely about thevertical posts 9, and springs 03 for operating the same, branch ropes nfrom the main cable d secured to the eccentrics h, and adj ustable anddetachable projections Z, to keep the eccentrics in place, all operatedsubstantially as and for the purpose described.
